Sometimes you can make these remarkable discoveries online…
I already knew this record existed, but now finally found a link for it; the 1916 recording of Thomas Beecham, conducting Stravinski’s Firebird.
* You read it right, 1916… *
Acoustic, no electricity used, only in the performance. Weird, to hear such “modern” music on an acoustic Columbia record.
Wow, was my first thought… :-)
